Martin from the USDA emailed a few more pictures from our last sampling trip. The next trip is in just less than 2 weeks. Carla, an Earth Sciences undergrad, is going to come out with me to sample and set up the Licor (measures CO2 respiration from the soil). She will be completing her undergraduate thesis working with me (Thanks Berry!). She'll examine alkalinity (or the inorganic carbon flux) associated with different landuse types we are examining: forested, corn till, corn no till, mixed, and unimproved pasture. She is also planning to compare this with samples gathered from Peru this summer. It should be an interesting study because both glacial and agricultural watersheds have high erosion rates.
